Some of us have been discussing the 914 rear suspension offline and I measured my toe curve yesterday. I figured I'd share it with the club for discussion.
The axle height scale is in inches and the zero is with the arm level. Attached image(s) |

Sorry, I meant to explain more, but I had to run out for a sec.
Yes, along the y-axis positive is jounce and negative is rebound.... but it all depends on your starting condition. If you start nose low (the trailing arm attachments to the chassis are lower than the centerline of the wheel) then your zero might be 1 or 1.5.... if you've moved your chassis mounts higher in vehicle your starting point may be -2. And the toe is relative, too. X-axis now... assume you start with zero toe, then look at the change in toe only. For example: if you set your car to zero toe and the axle center line is 1 inch lower than the chassis mounts... your zero is at -1 on the y-axis. As you jounce, the rear suspension toes out first and then goes back through zero toe, then on to toe in. I plan on measuring my front suspension, too, but it would have no relavance to a stock setup (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) |
